What this skill does

Uses the whois command to query registration information for a domain or IP address. Parses and organizes key fields — registrar/registrant info, registration/expiry dates, name servers, IP ranges (CIDR) — and outputs them in a report format.

When to use

  • When verifying domain ownership and registrar
  • When assessing takeover potential based on domain expiry dates
  • When identifying the ASN and organization associated with an IP address
  • When exploring related IP ranges (CIDR) to discover additional attack surface
